Photoaffinity labelling of cyanomethaemoglobin with derivatives of tryptophan and 5-bromotryptophan.

Abstract

Tryptophan and 5-bromotryptophan (5-BrTrp) are relatively potent inhibitors of sickle-haemoglobin polymerization. The binding sites of these compounds to normal and sickle haemoglobin (HBA and HBS) have been suggested, but not firmly established, through the use of spin-labelled derivatives and/or computer modeling. In the present study we approached the… (More)
